Explanation:
Data decapsulation is simply the reverse of encapsulation. This is when an incoming transmission (to be received by the destination computer) is unpacked as it moves up the protocol stack. The data at the bottom of the layer are packaged several times to ensure security.

Answer:
De-encapsulation takes place in receiving computer. In de-encapsulation process, header and trailer attached in encapsulation process are removed. Physical layer picks encoded signals from media and converts them in frames and hands them over to the data link layer.
